Nrog rau kev txhim kho thiab nthuav dav ntawm kev lag luam luam ntawv thiab cov kev xav tau ntawm cov ntawv thov hauv ntau qhov kev lag luam, daim ntawv thov txias bronzing thev naus laus zis hauv kev lag luam muag khoom tau txais kev thov ntau dua thiab kev txhim kho. Kev siv tshuab txias bronzing tau muab faib ua ob hom: DryLamination thiab WetLamination. Tus yuam sij rau cov txheej txheem ntau lawm yog UV nplaum thiab tshwj xeeb electrochemical hlau ntawv ci, uas tsis yog yooj yim raws li kev siv tshuab ntawm electrochemical foil coated nrog kub yaj nplaum.
DryLamination
Thawj daim ntawv thov tshuab txias stamping yog nyob rau hauv daim ntawv ntawm qhuav txias stamping. Daim ntawv thov kev siv tshuab ziab khaub ncaws qhuav yog ua cov duab ntawm lub substrate thiab siv lub teeb UV kom qhuav thiab ua kom cov kua nplaum UV rau ntawm cov coated substrate kom cov duab nplaum. , tam sim ntawd tig cov ntawv ci mus rau daim duab nplaum nrog lub pinch roller thiab tshem tawm cov ntawv ci tsis tsim nyog. Cov txheej txheem tseem ceeb yog raws li nram no:
1. Printing cationic UV adhesives ntawm web-raws li raw cov ntaub ntawv.
2. Ua haujlwm zoo ntawm kev kho cov nplaum UV.
3. Cov ntawv nyiaj txias stamping yog ua ke nrog cov khoom siv luam ntawv los ntawm kev siv lub siab rau cov menyuam.
4. Cais cov ntawv kub stamping uas tsis tsim nyog los ntawm lub substrate, tawm tsuas yog qhov xav tau kub stamping duab ntawm qhov chaw nplaum nplaum.
Thaum siv lub tshuab ziab khaub ncaws qhuav, kev kho ntawm UV nplaum tuaj yeem ua tiav sai, tab sis nws tsis tuaj yeem kho tau tag nrho. Nws yog ib qho tsim nyog los xyuas kom meej tias nws tseem muaj qhov sib thooj viscosity tom qab kho kom nws tuaj yeem ua tau zoo nrog cov ntawv ci kub stamping.
WetLamination
Daim ntawv ntub dej txias stamping yog luam tawm cov duab ntawm lub substrate thiab lub tsho tiv no UV nplaum, tom qab ntawd siv lub siab rau cov menyuam los txuas cov ntawv ci txias rau hauv lub substrate, thiab siv lub teeb UV kom qhuav UV kua nplaum ntawm lub substrate los ua cov ntaub ntawv txias. daim duab nplaum. Tshem tawm cov ntawv ci tsis tsim nyog. Cov txheej txheem tseem ceeb cov kauj ruam yog raws li nram no:
1. Kev luam tawm ntawm cov dawb-radical UV nplaum rau ntawm lub vev xaib substrates.
2. Siv cov ntawv txias stamping rau hauv ntu substrate.
3. Ua haujlwm zoo ntawm kev kho cov dawb-radical UV nplaum, vim tias cov nplaum nplaum yog sandwiched ntawm cov ntawv txias stamping thiab lub zos luam ntawv tam sim no, thiab UV teeb yuav tsum dhau los ntawm cov ntawv ci kub stamping kom ncav cuag cov nplaum txheej.
4. Cov ntawv ci kub stamping yog sib cais los ntawm cov khoom siv luam ntawv, thiab cov duab kub stamping yog tsim rau ntawm cov khoom luam ntawv. Vim tias cov txheej txheem ntub dej txias txias siv cov nplaum dawb-radical UV los hloov cov tshuaj cationic UV nplaum; Yog li ntawd, qhov pib adhesion ntawm UV nplaum yog muaj zog dua, thiab nws tuaj yeem nplaum dua tom qab kho; thiab kub stamping ntawv ci plating Cov txheej hlau yuav tsum muaj cov teeb pom kev zoo sib xws los xyuas kom meej tias UV teeb tuaj yeem dhau los thiab ua rau cov tshuaj tiv thaiv ntawm UV nplaum. Kev ntub dej txias stamping tshuab tuaj yeem siv rau hauv xovxwm luam ntawv.
